GROUP 76 ANALOG I/O CONFIG DESCRIPTION
76.01
76.02
Analog 1 Configuration
Analog 2 Configuration
All choices are available.
Do not duplicate.
PROC TRANS 2
Used for the Multivariable control functionality.
PROC TRANS 1
Used as the primary process transmitter for Control Mode.
EXT SETPOINT1
Used for the Primary External Setpoint
GROUP 75 PROCESS CONTROL
DESCRIPTION
75.02 PRIMING DELAY
The time that the drive will run at full speed to prime. All functionality except for VFD
protection is disabled during this time. The range is 0 – 6000 sec
75.03
SLEEP MODE
Defines the selections for SLEEP MODE.
DISABLED
Function is disabled.
MIN SPEED
Pump will enter sleep mode when the both the minimum speed and the process variable
is achieved.
INTELL SLEEP
Pump will enter sleep mode when the both the minimum flow and the process variable is
achieved. The PS220 will determine the correct value proportionally based on operating
speeds.
75.05
SLEEP VALUE
The percentage of the process value achieved while the PS220 runs at the minimum
speed setting before entering the sleep mode. Default is 100%. Range is 0-??? Applies to
75.03 = Min Speed.
The percentage of the process value achieved while the PS220 runs at the minimum flow
setting before entering the sleep mode. Default is 100% of minimum flow value. Range is 0-
??? Applies to 75.03 = INTELL SLEEP.
75.06 RESTART VALUE
The percentage value of the process variable that is allowed before the drive will resume
operation and restart from the sleep mode. Wake-up level in % of setpoint value = Range
is 0 – 500%. The default is 10%.
75.07 SLEEP DELAY
The time delay before the Ps220 will enter the sleep mode. Range 0-1800 sec. Default is 5
seconds.
75.08 RESTART DELAY
Time delay for the PS220 to resume operation and restart from the sleep mode. Range
= 0 –1800 sec. Default = 10 second
75.09 SETPOINT MIN
Defines minimum process control setpoint any value below this will not be used in the PID
control.
75.10 SETPOINT MAX
Defines maximum process control setpoint any value above this will not be used in the PID
control.
75.16
FLOW BYPASS SOURCE
Selects the signal source for activating the bypass relay.
OFF [DEFAULT]
Function is disabled.
FLOW ACTUAL
An external flow meter signal is used to control the bypass valve relay output.
SMARTFLOW
SmartFlow is used to control the bypass valve relay output.
75.17 FLOW BYPASS ON
This flow value that will trigger the Flow Bypass function. This value should be at full speed.
The PS220 will determine the correct value proportionally based on operating speeds.
Range = 0 – 100,000. Default is 0
75.18 FLOW BYPASS OFF RATIO
Defines the flow ratio for closing the Flow Bypass valve. Bypass valve closes when (Flow
actual/ Flow Minimum) >= Flow Bypass Off Ration. The default is 2.1. The range is 0.0
– 5.0.
75.19
ON DELAY The time delay to activate the flow bypass relay. Range 0 – 1800 sec. Default = 1 sec.
75.20
OFF DELAY The time delay to de-activate the flow bypass relay. Range 0 – 1800 sec. Default = 1 sec.
75.21 FLOW RELAY START DELAY
The time delay that the flow must be below minimum flow to activate the Flow Bypass
function. Range 0 – 200 sec. Default is 15 seconds.
75.22 PRESS INC SPEED
This the speed at which system curve compensation begins. At speeds below this, no
compensation for increased resistance is made. The range is 0-3600rpm. 1200rpm is
default.
75.23 PRESS INC % TIME
This the amount that PumpSmart will have increased the setpoint at maximum speed. The
range is 0-100%. 0% is default.
75.24
MULTIVAR CTL
Selects the PS220 Multivariable Control feature.
OFF [DEFAULT]
Disables Multivariable control
ON
Multivariable control is active
75.25 MULTIVAR REF SOURCE
This parameter defines the source used in the Multivariable control function. Choices are
from any available Analog Input. The selected Input will need to be fully configured as
“Proc Trans 2”
75.26 LEVEL 1
This is the first level in which the Multivariable control function will scale the set-point as it is
defined by the LO INTRCPT value and SPT LO value. LEVEL 1 is defined in units of the
secondary process variable. Range: -10000-10000 Default = 0.
75.27 SPT LO
This is the lower limit set-point as related to LO INTRCPT. SPT LO is defined in units of the
primary process variable or RPM when in speed control. Range: -20000 -20000 Default =
0.
75.28 LO INTRCPT
This is the lower limit level in which the Multivariable function will scale the set-point as
defined by the SPT LO value. LO INTRCPT is defined in units of the secondary process
variable. Range: -10000 to 10000 Default = 10000.
75.29 LEVEL 2
This is the upper level in which the Multivariable control function will scale the set-point as
it is defined by the HI INTRCPT value and SPT HI value. LEVEL 2 is defined in units of the
secondary process variable. Range: -10000 to 10000 Default = 10000.
75.30 SPT HI
This is the upper limit set-point as related to HI INTRCPT. SPT HI is defined in units of the
primary process variable or RPM when in speed control. Range: -20000 to 20000
Default = 20000.
75.31 HI INTRCPT
This is the upper limit level in which the Multivariable function will scale the set-point as
defined by the SPT HI value. HI INTRCPT is defined in units of the secondary process
variable. Range: -10000 to10000 Default = 10000.
